Опорное кольцо цилиндра с внутренним диаметром 101,59 мм Caterpillar 6377848

The Cylinder Backup Ring prevents hydraulic fluid from leaking, ensuring the system operates at full efficiency. By reducing friction between the piston rod and the cylinder wall, the backup ring protects the seals from excessive wear and tear. This contributes to the longevity of the seals, grooves, and overall hydraulic system, which is necessary for the performance and safety of equipment.Attributes:• Prevents extrusion of seals under high pressure.• Provides support to hydraulic seals during operation.• Protects seals from damage due to high-pressure fluctuations.Applications: The Cylinder Backup Ring is located inside the hydraulic cylinder, positioned between the piston and the cylinder wall, and acts as a secondary seal to reinforce the primary sealing function of the hydraulic system.
